Application filed February 8, 1919. Serial No. 275,861.9..Y

The invention relates to devices for supplying grease or lubricating material to engine bearings and is designed to facilitate the operation of supplying the lubricant and also provide for the stability of the y parts.

In the drawings Figure 1, is anelevation or side view of my device.

Fig. 2, is a vertical cross-section of Fig. l with the cover unlocked.

Fig. 3, is a detached View of the cover and top of cup. n

Fig. 4, is a top view of Figs. 1 and 2 with the detachable cover plate removed.

Fig. 5, isa separate view ofV the cover plate.

Fig. 6, is 'a separate view of the securing plate and Fig. 7, is aseparate -view'of the coverl handle plece.

. In the use ofgrease cups, it is important that the grease receptacle should always be available for use. In many cases the upper portion or deep cap holding the grease'is readily unscrewed or detached from the stock or base which is the part xed to the bearings. The grease container is usuallyV connected with the stock by being screwed or slipped onto it after the cup is filled with the grease, and the grease is .then fed to the bearing by screwing the upper half farther on the. body portion of vthe cup. In devices of this construction the grease holding cap is often misplaced or lost, when once removed from its stock and is also difficult to fit in place, after being filled with grease, as the screw threads fail to readily take hold.

Another important point is that the grease holding cup is often loosened and lost by jarring of the machine.

The improved device embodies the use of a grease receiver and holder which is not removed from the stock or body of the cup.

In the drawings A, represents the stock or base of the device which is hollow and provided at its narrow end` with an exterior threaded terminal a, designed to be screwed into the bearing; the bearing not being shown.A For this purpose the middle portion is made hexagon on its exterior at al.

The upper part of the stock or base A, is broadened out and terminates at its top in a projectingrim b, having an vexterior threaded surface. The lower end has an outlet c, to convey the lubricant to the bearing.

Secured to the base A, is the grease container B, which is threaded on its interior surface to match the threaded rim I). In constructing my device when the grease container B, is fitted onto the base4 A, its lower portion is screwed past the rim '6. The lower thread. b1 is then turned in or mutilated so it cannot be removed by unscrewing but is permanently locked to the base A. Even where the entire device is removed from the bearing the cap and stock will not be separated in general use. The top of the grease container B, has an inwardly projecting rim C, with an irregular shaped opening as shown in Fig. 4, com-- prismg a circular center g, and bays g1 g1 on opposite sides of its circumference. Adapted to lit in this opening is a cover plate IZ, the outer part of which extends over the rim C and has a depressed or countersunk central portion of the same contour as the opening g, g1, in the rim C, and a circular central opening g, less than the area of the circular part of the depression in the plate d.

Adapted to lie in the cental part of the depression g, of the cover d, is a circular plate ZL, and on the under side of the cover d, is a catch plate i; the plan of which is shown separately in Fig. 6. This catch plate c', is greater in circumference in its central part than the opening gn, and has wings Za, l.: and is punctured at its central portion within the radius of the opening gl forming holes Z, Z which register with corresponding openings in the circular plate h.

A handle or thumb piece m, for the cover plate'is shown separately in Fig. 7. It has two projections 0, o, on its lower part which are positioned to pass' through the openings h, ZL, in circular plate L, and the openings Z, Z in the catch plate z'. and th'e openings Z, Z, and 71.1, h1, in the plate 71., and c' beingwithin the radius of the central opening gn, of the cover plate d. The elements (Z, it, z', and m are secured together by passing the projections o, o, through vthem and riveting the ends of 0, '0. rlilhis vl, will contact, thereb forming a means for n the fingers to turn tie grease container B by the handle m, when desired and which will screw it down to feed the grease to the bearing. The handle ma, is also used to unscrevv the receiver B When empty, .to its limit, but by reason of my novel construction of cover when thus unscrevving, the catch plate e', Will be turned and released and the entire cover plate d entirely loosened before sufficient pressure is exerted to jam the broken or mutilated thread at the bottom of B on the threads of the base A., At one side of the grease container B, near the outer circumference the rim and the cover plate are'` pierced With holes s, s, and a ring r, is vinserted which passes through both and ties them together. This insures their proper replacement even in the dark after the grease cup has been filled.

By the foregoing description it Will be seen that the interior of the grease receiver is readily accessible for filling and the contents may be easily forced to the bearing by manipulating the handle m. The grease container is inseparable from its base and the cover is attached to it so that neither are subject to loss, or the disadvantage of fitting together.

in referring to the lower thread of the grease container as being mutilated, it is meant that the-revolution of the tap shall* 4the rim by circular movement and a base threaded to receive the container and permanently fastened thereto, substantially as shoivn and described.

2. In a grease cup of the class shown a grease container having in combination a cylindrical body with an inwardly projecting rim C and a lubricant confining cover composed of the catch plate element z', sliding plate It, cover plate al, and a handle element Im, substantially as and for the Ipurposes shown and described.

ln a grease cup of the class shown, the threaded base plug A, the threaded grease container B, with mutilated lower thread and having an inwardly projecting rim C, in combination With a lubricant confining cover composed of the catch plate lement c', sliding plate h, cover plate (l, and a handle element m, together with a stop projection 1), located on the rim C, s0 as to arrest the revolution of the catch plate e',

substantially as shown and described.
